a.
Having but one flagellum; as, uniflagellate organisms.
n.
A cyst in which some unicellular organisms temporarily inclose themselves, from which they emerge unchanged, after a period of drought or deficiency of food. In some instances, a process of spore formation seems to occur within such cysts.
n.
The power possessed by living organisms, both animal and vegetable, of adapting themselves to modifications or changes in their environment, thus possibly giving rise to ultimate variation of structure or function.
n.
A minute grain or germ; a small, round or ovoid body, formed in certain organisms, and by germination giving rise to a new organism; as, the reproductive spores of bacteria, etc.
n.
any preparation used to render an organism immune to some disease, by inducing or increasing the natural immunity mechanisms. Prior to 1995, such preparations usually contained killed organisms of the type for which immunity was desired, and sometimes used live organisms having attenuated virulence. since that date, preparations containing only specific antigenic portions of the pathogenic organism are also used, some of which are prepared by genetic engineering techniques.
a.
Not organized; being without organic structure; specifically (Biol.), not having the different tissues and organs characteristic of living organisms, nor the power of growth and development; as, the unorganized ferments. See the Note under Ferment, n., 1.
a.
Belonging to the same category of individuality; -- a morphological term applied to organisms so related.
n.
A genus of minute, pale-green, globular, organisms, about one fiftieth of an inch in diameter, found rolling through water, the motion being produced by minute colorless cilia. It has been considered as belonging to the flagellate Infusoria, but is now referred to the vegetable kingdom, and each globule is considered a colony of many individuals. The commonest species is Volvox globator, often called globe animalcule.
n.
The study or science of the life of marine organisms.
a.
Pertaining to histology, or to the microscopic structure of the tissues of living organisms.
v. t.
To destroy all spores or germs in (an organic fluid or mixture), as by heat, so as to prevent the development of bacterial or other organisms.
n.
The science which treats of the complex relations of living creatures to other organisms, and to their surrounding conditions generally.
n.
Manner of organization; the arrangement of the different tissues or parts of animal and vegetable organisms; as, organic structure, or the structure of animals and plants; cellular structure.
n.
The tendency to undergo change, characteristic of both animal and vegetable organisms, and not restrained or cheked by the environment.
n.
One of a class of vegetable organisms, in the classification of Cohn, which includes all of the inferior forms that multiply by fission, whether they contain chlorophyll or not.
a.
Developing, in the case of multicellular organisms, from the same embryonic systems into which the secondary unit (gastrula or plant enbryo) differentiates.
a.
A morphological term signifying development, in the case of multicellular organisms, from the same unit deme or unit of the inferior orders of individuality.
a.
Symmetrical bilaterally; -- said of organisms, or parts of organisms, capable of division into two symmetrical halves only in a single plane.
n.
A genus of bacteria found in various organic fluids, especially in those those of the stomach, associated with certain diseases. The individual organisms undergo division along two perpendicular partitions, so that multiplication takes place in two directions, giving groups of four cubical cells. Also used adjectively; as, a sarcina micrococcus; a sarcina group.
a.
Not having any of the distinct systems or types of structure, as the radiate, articulate, etc., characteristic of organic nature; as, all unicellular organisms are systemless.
